With two new LNG mega-projects—Venture Global Plaquemines in Louisiana and Cheniere Corpus Christi Stage 3 in Texas—now operational, the American natural gas landscape is undergoing a dramatic shift. This expansion has already started to drive significant new feedgas demand.
SynMax clients who use Hyperion, the industry's premier Oil & Gas intelligence platform, are uniquely positioned to analyze and understand this changing environment. With the latest additions of Leviaton and Hyperion Agent, all Hyperion clients can now gain unparalleled insights into domestic production, feedgas, and LNG flows.
Hyperion clients also get a 20% discount on Vulcan. The most advanced infrastructure watch platform. We included several satellite images from Vulcan in this report.
Introducing the new features of Hyperion:
We utilized Hyperion Agent (currently in beta) to investigate the record-breaking feedgas demand and assess if the market is prepared for this rapid LNG expansion. One of our first queries was to create a visualization of current feedgas demand and compare it to previous years, a task Hyperion Agent completed seamlessly.
With record feedgas and growing LNG liquefaction capacity in the U.S., we wanted to examine this trend and analyze how the market prepared for the expansion using the Hyperion platform.
Venture Global Plaquemines LNG
Capacity: 13.3 MTPA (Phase 2: 18 small scale liquefaction trains)
Location: Plaquemines Parish, Louisiana
Feedgas Requirement: ~1.7 Bcf/d
We asked Hyperion Agent a critical question: Did Plaquemines adopt a "build it and they will come" strategy for feedgas, or was the demand carefully planned in consideration of upstream well activities and production timelines?
Hyperion Agent's analysis, supported by a detailed chart, confirmed that the strategy was, in fact, planned.
However, we noticed that Haynesville production did not climb significantly to account for all this new feedgas. We then asked Hyperion Agent to reconcile the 3 Bcf/d increase with the approximate 1 Bcf/d increase in Haynesville production.
Hyperion Agent's response provided a clear reconciliation:
Because most of the “+3 Bcf/d” you’re seeing is Plaquemines ramping, while other LNG plants reduced flows. Net U.S. LNG feedgas rose by much less, and the supply to cover that net increase came from multiple basins, not just Haynesville.
Key evidence (7-day averages, since Plaquemines start 2024-12-16 to latest 2025-08-22)
- Plaquemines LNG: +2.79 Bcf/d
- Rest of U.S. LNG: -1.36 Bcf/d
- Net U.S. LNG feedgas: +1.43 Bcf/d (= 2.79 − 1.36)
Supply moves over same window
- Haynesville dry gas: +0.31 Bcf/d
- Permian: +0.66 Bcf/d
- Gulf of Mexico: +0.11 Bcf/d
- Appalachia: +0.05 Bcf/d
- U.S. total dry gas: +1.48 Bcf/d ≈ Net LNG +1.43 Bcf/d
Why this reconciles
- The “+3 Bcf/d” is essentially Plaquemines’ own ramp. Other LNG facilities had maintenance/outages and step-downs that subtracted ~1.4 Bcf/d, so total LNG only increased ~1.4 Bcf/d.
- Haynesville contributed modest growth; the balance came mainly from the Permian (plus smaller lifts elsewhere), collectively covering the net LNG increase.
Caveats
- LNG feedgas here reflects interstate scheduled deliveries; intrastate-only volumes aren’t captured.
- Exact deltas depend on the chosen start date and whether you use daily vs 7-day averages.
The analysis highlights a key dependence on other LNG facilities not operating at full capacity. We then asked the agent to visually prove this point, which it did by generating a relevant chart.
We further verified this insight by cross-referencing with the vessel movements for Cameron, Sabine Pass, and Freeport in the Leviaton model, confirming the accuracy of the data.
Capacity: 4.92 MTPA (For 3 Liquefaction Trains)
Location: Corpus Christi, Texas
Feedgas Requirement: ~0.66 Bcf/d
While our initial analysis of interstate flows showed a decrease at Corpus Christi, this only tells part of the story. SynMax, in collaboration with Criterion, has used their pipeline dataset and our Leviaton LNG model to uncover the full picture behind Corpus Christi's operations, providing a more complete narrative for our clients. This is in the works to be embedded in our dataset.

In an era of significant expansion for the U.S. natural gas landscape, two major LNG projects—Venture Global Plaquemines in Louisiana and Cheniere Corpus Christi Stage 3 in Texas—are now operational, leading to a surge in feedgas demand. SynMax's premier oil and gas intelligence platform, Hyperion, with its new features Leviaton and Hyperion Agent, offers a unique and powerful way to understand this market shift. We utilized Hyperion Agent, an advanced conversational AI, to analyze this trend, confirming that the market's response was a well-planned strategy. By cross-referencing this data with Leviaton's insights on global LNG flows and Vulcan's satellite imagery, we were able to fully reconcile where the increased feedgas demand was being met and how it was affecting the broader market. SynMax clients have unprecedented access to information and analytical tools once thought unavailable.
